摘要:
An organic super-conductive material and a process for producing the same are disclosed, the material comprising a polymer having dispersed therein an organic super-conductive substance comprising an electron donor and an electron acceptor.
摘要:
An organic thin film and process for making the same, having electroconductivity, semiconductivity or superconductivity. The film is made of vapor-deposited bisethylenedithiatetrathiafulvalene (BEDT-TTF) by heating BEDT-TTF at a pressure of 10.sup.-2 Torr or below and at a temperature not higher than 260.degree. C. The temperature of the substrate on which the vapor is deposited is held at a lower temperature than the vapor. A thin film produced under these temperature and pressure conditions contains substantially no decomposition product. The electroconductivity of the film can be adjusted by selecting the substrate used for vapor-deposition of the film and the electron acceptor used as a dopant of the film. In order to achieve a vapor-deposited film with a high degree of orientation, silicon wafer is preferably used as a substrate for the film.
摘要:
A process for producing an organic electrical conductor comprising the steps of: (1) dissolving or dispersing an electron-donating material and an electron-accepting material in a solvent containing an alcohol; and (2) forming and growing crystals of the organic electrical conductor by subjecting the dissolved or dispersed materials of step (1) to electrochemical oxidation-reduction.
摘要:
A plastic optical fiber comprising a core of a copolymer of an alkyl methacrylate and a styrene derivative and a cladding of a copolymer of vinylidene fluoride and a perfluoroolefin provided on the core, the copolymer of the cladding having a melting point of at least 120.degree. C. and a perfluoroolefin content in the range of from 3 mol % to 70 mol %.
摘要:
A self-bonding magnet wire comprising a conductor and a baked mixture of nylon copolymer (A) and nylon copolymer (B) where the proportion of nylon copolymer (A) and nylon copolymer (B) is 50-95 parts of (A) to 50 to 5 parts of (B) (by weight), nylon copolymer (A) being alcohol-insoluble and non-swellable by an alcohol at room temperature and containing nylon-12, and nylon copolymer (B) having a lower melting point than that of nylon copolymer (A). Yoke coils for television sets comprising such a magnet wire and a process for forming such a magnet wire are also disclosed.
